can't find "File Requests API"

I would have liked to use the file request api for requesting files from a client. The client creates an order on a website, and part of this includes that the client should attach some files.

So if we could have sent a separate email with a file request using the API that would have been awesome - so we didnt have to do the upload script and email attachment ourselves.

Anyway.. not in the near future it seems :)
